For laptops, if you are running a full-screen application on relatively low battery, when the low battery warnings pop up you may not see them at the same time, the keyboard may become unresponsive. Low batteries can affect the functionality of laptop keyboards via some indirect circumstances, and wireless desktop keyboards. This kind of problem breaks down primarily into four areas: Low Battery, Physical Damage, Driver and Software issues, and Firmware Issues. Like for example I press the play button and it goes to expose, or I press the volume button and it goes to the desktop. This is not a common problem, but when it happens, either some or all keys stop working (depending on the situation), or features of the keyboard such as backlighting may not work.Īpple Discussion poster " rikardo Burciaga" writes: "I am having trouble with the keyboard but only with some keys. For various reasons, keyboards on both laptops and desktops may suddenly stop functioning properly.
